SIDNEY L. NEFF, OF SALT LAKE CITY, UTAH.

BILLIARD-CUE CHALKER.

I Specification of Letters Patent.

Patented June 6, 1916.

Application filed September 1, 1915. Serial No. 48,486.

To all w hom t may concern:

Be it known that I, SIDNEY L. NEFF, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented new and useful Improvements in Billiard-Cue Chalkers, of which the following is a specication.

My invention relates to billiard cue chalkers, and has particular application to an automatic chalker.

The principal object of my invention is to provide a cue tip chalker whereby the chalk will be rotated when placing the cue tip thereagainst, thereby insuring a thorough chalking of the tip.

Another object of my invention is to provide a device of this character which may be angularly adjusted to any desired position so as to facilitate the easy insertion of the cue within the chalk cup. Y

Another object of my invention is to provide a device of this character whereby the chalk may be securely held within the cup and removed therefrom when desired.

Another object of my invention is to provide a device of this character which will be so constructed as to permit of replacing worn or broken parts without incurring great expense, the parts being adjustable so as to permit the eflicient operation ofthe device.

lVith these and other objects in view, which will appear as the nature of the invention is more fully understood, the invention consists in the novel features of construction and arrangement of parts hereinafter described and illustrated in the accompanying drawings, in which:

`Figure 1 is a side elevation of my device; Fig. 2 is a longitudinal central section; Fig. 3 is a vertical section taken on the line A-A; Fig. 4C is a detail perspective view of the lug carrying ring; Fig. 5 is a detail view of the chalk holder, showing the chalk removed; Fig. 6 is a detail perspective view of the adjustable bracket; Fig. 7 is a detail perspective view showing the socket supporting bracket and its connection therewith; and Fig. 8 is an end elevation of my device showing the cup. j

Referring to the .drawings in detail, 1 designates a base or any suitable support to which is secured my chalker. y In the present instance I have shown my chalker arranged in horizontal position, but I wish it to be understood that it may be arranged in any desired position that the user may elect.

Secured to the base in any suitable manner, such as by bolts, screws or the like, is a bracket 2 which is formed of any suitable material, such as aluminum, steel or the like. The upper end of the bracket 2 is provided with an upwardly extending lug 3 which has the inner face thereof serrated.

4 designates an annular socket which is interiorly threaded and has a rearwardly extending ear 5 thereon, to which is connected a lug 6, the inner face of said lug being serrated. The socket A is pivotally mounted upon the bracket 2 by means of securing the confronting faces of the lugs 3 and 6 serving to lock the socket in any desired position.

Threadedly secured within the socket 4 is one extremity of a longitudinally extending tubular casing 8. Supporting the oppo- 'site end of the tubular casing 8y is a vertithe lug 6 to the lug 3 by means of a bolt 7',VA f

Vsa

forations in either member being adapted to f receive a bolt 12 lwhich is adapted to lock the bracket in any of its adjusted positions. The upper end of the arm 11 is provided with a vertically disposed split ring which has the terminals 13 thereof bent outwardly to lie parallel to each other, each of said terminals being provided with eyes adapted to receive a screw 14 for clamping the tubular casing within the ring. n

Secured within the tubular casing 8 is a tube 15, at one end thereof being provided with an annular boss 16 which threadedly engages the inner wall of the casing 8. This boss serves to keep the tube 15 in spaced relation to the casing throughout .its en-V tire length. The opposite end of the tube 15 is provided with an annular recess upon the inner face thereof which receivesthe ring 17. Formed on the inner face of the ring 17 are a pair of inwardly extending lugs 18. In the present instance I have only shown two lugs, but it will be understood that any number may be used.

Slidably mounted within the tube 15 is a shaft 19 which is provided with a spirally arranged groove 20. One end of the shaft 19 is provided with a ring or washer 21 which is adapted to keep the shaft in spaced relation to the inner wall of the tube 15, thereby eliminating friction. The outer extremity of the shaft 19 is threaded to receive a nut 22 which is provided with an annular flange 23 on the inner face thereof.

Mounted upon the shaft 19 is a helical spring 21 which has one end thereof contacting with the end wall of the tube 15, the opposite end abutting the inner face of the flange 23. Permanently secured to the outer face of the flange 23 is one end of a tubular sleeve 25, the opposite end being arranged for sliding movement between the collar 15 and the casing S. This tube not only acts as the cover for the shaft 19 but acts as an additional support for the shaft, thereby keeping the shaft in its proper position with respect to the tube.

26 designates my improved form of chalk holder which is provided with a rearwardly extending annular collar 27 having the inner walls thereof provided with threads to engage the threaded extremity of the shaft 19. When the holder is in its proper position upon the shaft 19 the outer face of the 4annular' collar 27 lwill contact with the nut 22, thereby preventing backward movement of the nut 22 upon the shaft. The chalk holder 26 is preferably of annular formation and is provided with a rectangular recess 27', each of the walls of said recess being provided with. a leaf spring 28. Each side of the holder 26 is provided with slots 29 which communicate with the interior of the rectangular recess. Pivotally mounted upon the walls of each of the recesses 29 is a bell crank lever or trigger 30 which has one arm f thereof normally lying in the bottom of the recess, the remaining arm being arranged eXteriorly of the casing and having its free end bent outwardly to form a grip. The holder 26 is provided with an annular flange 31 which is flared outwardly to facilitate the insertion of the cue within the holder. In the preferred embodiment of my chalk holder 1 have shown the rectangular recess to receive chalk of a corresponding configuration, but 1 wish it to be understood that 1 do not limit myself to this form as 1 may provide the holder with. a circular lrecess to accommodate chalk of the same formation.

From the foregoing construction it will be seen that when the block of chalk is placed within the holder the leaf springs which are disposed on the walls of the recess will engage the surfaces of the chalk, thereby retaining the chalk securely within the holder. The operator having placed the cue tip against the surface of the chalk by forcing the cue forward the chalk holder 26 will be moved rearwardly and the shaft `19 will slide within the tube 15 against the tension of the spring 24C, the inner surface of the socket et limiting the movement of the shaft. Owing to the fact that the shaft is spirally grooved and that the walls of the groove engage the stationary lugs which are formed by the ring 1S, the shaft will be caused to rotate during its upward movement, thereby imparting a similar motion to the chalk holder. The chalk being held securely within the holder, the engaging face of the chalk will be rotated against the surface of the tip, thereby causing the latter to be thoroughly chalked. The shaft having completed its upward stroke, the cue is relieved of its upward pressure, thereby permitting the helical spring 24: to retract. This forces the shaft downwardly out of the tube 15 and causes the chalk holder to return to its normal position.

1f it is desired to remove the chalk from the holder after it has spent its life of usefulness, by gripping the handle of the fulcrum levers at the out-turned end portions and pushing the arms-outwardly the inner arms of the levers which lie within `the recess beneath the chalk will be moved downwardly, thereby forcing the chalkout of the holder.

1f it is desired to move the chalkingapparatus to a more advantageous or convenient angle with respect to the base, the bolt 12 is moved from the perforations of the adjustable bracket, thereby permitting the chalker to be moved outwardly upon its pivot, where it will be locked by inserting the bolt in the perforations, thereby clamping the movable arm of the bracket 11 upon the upstanding portion 9.

By providing the tube A15 with a detachable ring 17 carrying the lugs 18 1 have made it possible to replace the lugs in case they become broken Aor worn without incurring any great expense.

The fact that the nut 22 is threadedly mounted upon the outer extremity of the shaft 19 permits the nut to be fed upwardly, thereby regulating the tension of the helical spring 24 in case the latter may loose its retractile force as a result of its repeated use.

1t is thought from the foregoing that the construction and operation of my cue chalker will be thoroughly understood without further description, and various changes in the size,lshape, proportion and minor details in construction maybe made without departing from the spirit and :scope of the claims appended thereto.

Having thus described my invention, 11
